im pretty sure i know the answer, but just want to confirm coz a friend is doubtful.
i would say the standard has become the 6:5 blackjack esp. on the strip.
the 3:2 tables are out there sometimes it takes some searching to find them. for example at the nugget a 3:2 was between 6:5 tables, no other differences, right in the party pit near the sportsbook. at binions they had one table that was 3:2 all the others were 6:5 [20+].
